I think it’s quite unclear whether school will be fully remote- it depends on how the variants affect us, rates of vaccinations etc. I would assume that regardless, most social work placements will be at least partly in person. If you’ve landed a FT job you’re really excited about, I see no harm in deferring your acceptance to UofT. More work experience in the field is always good- and is a great opportunity to clarify your career interests. That way you may have a better idea of what you want to get out of your masters when you do get it.
